Be it v'known thatl Ig, JOHN` T. Loenwoon, a' Acitizen of the United'A Statesand a' resident `of the" borough' of Brooklyn, city of New-York, county o f'Ki-ngs', and State'of` invented certain new and useful@ Improvements l Space-,Bands for in-gis 'a speci-@cation g v My.- inventionrelates toace'f'bandsfor ly` for linotype i bands. areiuseditov justify thezlin'es-of matrices'v and to llockthem up duringv the casting. of' the slugs,'=afterl which they aregenerall j' Vreturned tof-'la' magazine (lover"againl -The principal object. of'my-1invention'-is t0 Lprov'idea space bandwhich may`=`be madeat v -a much lower 'cost than heretofore. .Heretofore., space bands have-been in ividually shapedi-and finished from' arsol d barv 'ofsteel ;I :and their manufacture"l entailed `conx siderable machine work because they must..

necessarily be accurate in shape'and proper-F jl'tions.- 'sively used and Vhave ,tol be' replaced from.l

InasmuchA as' space bands are exten# ytime to time as'theypbecome worn or broken,"

v'their cost ofm'anufa'cture is an important` factor in the art.

Under my invention .the f Wedges,.iwhich constitute themore expensive. part of-thecomplete band, may be .made by a stamping method, by` cutting'fa'blank of' *sheetnmetal in a suitable cutting die and .then shaping it in'aforming d1e. When shaped, the wedges may be ground on'their 'opposite:faces and 'edgesl to reduce all the- Wedges to .a uniform thickness and. a-'uni- 4form width.'` 'When the wedges are shaped 'as herein shown and described, they will be rigid and strong enough to` serve 4their pur-v pose and,l in fact, will be equally'asdurable as space bands no w made bythe more" expensive methods`- There is a saving not only 'Y inthe cost of the Wedge, butin the entire space band, because"it is .not'necessary under my invention to. form` a dovetailed 4connection between-the'slide and vwedge by .the expensive planing method. .These results are Vattained: by stamping the. wedge with* Specification of Letters Patent. f 'Appnation meqnpr'pil 21,-, 1913.

The space band 1,' consists of a wedge 2 anda slide' 3, 4which are here shown as lformed to conform to the requirements l.of

the composing machines now in general use; but 1t is tobe understood that' changes may for other kinds of composing machines; and

lowing detaileddescriptionfis not intended to limit the scope-fof m-y invention -to this exact form.

f Thev wedge 2 yis formed of sheet metal which is preferably .of equal thickness throughout, at least before the wedge is 'ground as hereinafter set forth. The wedge has'the usual longitudinal slot in which -the holding member of the `slide moves; and on either" side of this slot 'the wedge is corru gated, *the corrugations extending y length,

wise'. thereof. The broad feature of vmyrinventlonuresides in the fact that the Wedge is corrugated lengthwise,

will'A have sufficient lateral 'strength and rigidity. to meet/requirements. The lon-giof themetal are preferably tangularly arranged, dat walls.

, At the .edges'of the walls 8, 9 opposite the web 4 the metal plate turns, preferably atv right angles, and forms the webs 12, 13, which extend laterally in opposite directions, and in the same plane. These walls 1,2, 13 are preferably -of uniformv width A throughout and constitute the opposite face of the wedge to the web 4. At the outer edges of the ywebs 12, 13 the plate turns up wardly, preferably at right angles theret 1,

. forming the vertical walls 14, 15 which lire preferably parallel with each other and cerminate in the free edges 16. The walls 14, 15 decrease in height'from the bott'f/m 10. of the wedge toward the top 11, where'they may entirely disappear or `terminate as flat metal. Atthebottom of thewedg the walls y14, 15 preferably turn inwardly' at 17 'and passes through the slot 5. On the surface4 of this `shollder Ithere is secured a block 21, preferably by means of a rivet 22 passing through the block and slide. The block 21..

is of greater width'than the slot 5 and it travelsv against the opposite face of the web 4 to that of thel slide. I prefer to make this block sufficiently wide to contact with the inner faces ofthe walls 14, 15.'l It has a movement lengthwise of the wedge, equal to the length of the slot 5.

By constructing the device as herein shown, it is unnecessaryto provide'a dovetail connection between the block 21 and wedge, as is. customary under the present lexpensive method.

After the wedge has been formed it may be ground on both "faces to make itsmooth and so that allwedges may be reduced to equal dimensions. It may also'be ground upon its opposite edges, z'. e., along the outer faces of the walls 14, 15 to make them smooth and to reduce Aall wedges to the same width. The grinding will also sharpen the edges 23. i f

The space band may be used in exactly the same manner and on the same machines as -space bands now in use and they are, in fact., interchangeable therewith; and therefore a description of their use` need not .be set forth herein..

From' the above it will be apparent that the vwedge is corrugated lengthwise, thereby permitting the same to be made sufficiently strong and rigid and by a stamping process,

and this constitutes the broad;'feature of my invention. The longitudinal corruga- "tions rre o". decreasing depth, so that the deviceA is wedge shaped. l i .Thewalls 8, 9 and web 4 form a groove or pocket 24 within the confines of which the block 21 may travel and be held; and *nis groove is preferably oper. to one face ofthe wedge. The walls 9, 13- a n'd15on the 'other hand form a longitudinal groove 25 which is preferably open to the opposite face of the wedge to that ofgroove 24. The walls 8, 12 and 14-also form allongitvudinal lgroove26 which is preferably opento the same face of the wedge as the` groovel25. The' walls 8, 9, 14 and 15 make thepwedge rigid laterally, -or in' its smaller dimension, ,thereby -making it sufficiently strong and rigid forfits purpose. g
